      abstract     = {Global warming poses a significant impact on plant species
                      in the Cerrado, the largest savanna in the world. However,
                      there is still a gap in understanding how species
                      distribution patterns are associated with their thermal
                      sensitivity. One approach to address this is quantifying
                      species´ specific responses through leaf traits related to
                      heat stress. Therefore, we determined the temperature that
                      caused a $50\%$ reduction (T50) in the light-acclimated
                      quantum efficiency of PSII (Fv′/Fm′) and the thermal
                      safety margin (TSM) (T50—maximum leaf temperature),
                      together with Leaf Area (LA) and Leaf Mass Area (LMA) in 12
                      tree species from two climatic contrasting regions within
                      the Cerrado. We compared the traits between widespread
                      species (co-occurring in both sites) and species restricted
                      to each region, and we explored the relationships between
                      T50 and TSM with LA and LMA. As a result, we found that T50
                      and TSM values were similar across species, regardless of
                      study region or species distribution range. Additionally, we
                      observed that study species had lower TSM, which suggests
                      that these species might be likely to approach
                      high-temperature thresholds. Furthermore, the study species
                      exhibited general relationships between LA and LMA with T50,
                      indicating that leaf traits mainly determine the thermal
                      properties of Cerrado tree species.},
